Abstract

A dispersed decision-making system that use knowledge accumulated in separate knowledge bases is considered in this paper. The system has complex and dynamic structure. In previous papers, different fusion methods were applied in this system. The novelty of this paper is to examine an approach in which many different fusion methods from the rank or from the measurement level are used simultaneously in one decision-making process. The obtained results were compared with the results obtained when fusion methods are used individually. In addition, the results were compared with an approach in which a dispersed system is not used, but the classifications generated based on each local base are directly aggregated using fusion methods. The conclusions indicated the legitimacy of the use of a dispersed system.
